#47848 [NEW]: importNode doesn't preserve attribute namespaces

From:             robin2008 at altruists dot org
Operating system: Ubuntu
PHP version:      5.2.9
PHP Bug Type:     DOM XML related
Bug description:  importNode doesn't preserve attribute namespaces

Description:
------------
I was expecting importNode to preserve attribute namespaces.
It doesn't

Reproduce code:
---------------
<?php
// PHP 5.2.* namespace bug - importNode doesn't preserve attribute
namespaces

$aDOM= new DOMDocument();
$aDOM->appendChild($aDOM->createElementNS('http://friend2friend.net/','f2f:a'));
echo 'DOM to add into is '.$aDOM->saveXML().chr(13);

$fromdom= DOMDocument::loadXML('<data xmlns:ai=" http://altruists.org "
ai:attr="namespaced" />');
echo 'Dom to import from is'.$fromdom->saveXML().chr(13);

$attr= $fromdom->firstChild->attributes->item(0);

$aDOM->documentElement->appendChild($aDOM->importNode($attr));
echo 'Result is '.$aDOM->saveXML();

// The following script gets round this bug

function importAttrNS($targetNode, $attr)
	{ // Last modified 2009-01-26	Imports an attribute without losing the NS,
if present
	if ($attr->prefix=='')
$targetNode->appendChild($targetNode->ownerDocument->importNode($attr));
	else
$targetNode->setAttributeNS($attr->lookupNamespaceURI($attr->prefix),
$attr->prefix.':'.$attr->name, $attr->value);
	}
?>

Expected result:
----------------
The imported attribute should keep its namespace.

Actual result:
--------------
The imported attribute becomes unnamespaced.
